Hello! In order to build the nimlsp, you need to have nimsuggest installed. They go into more details in their README. I'm not familiar with Nim myself, but I remember reading that they recommended using choosenim to install nim, as it will include all useful nim sources.

I already have nimsuggest installed.

% nimsuggest --version

Ah ok, hmm interesting. It seems like it assumes that nimsuggest exists at ../../nimsuggest/nimsuggest.nim, relative to the path of the nim executable. Not sure why, but I guess that's the structure in which choosenim installs things. What does the following produce:

% which nim
% which nimsuggest

[blakat360]

% which nim                                                                                                                                                                                                                                                                   
/usr/bin/nim
% which nimsuggest                                                                                                                                                                                                                                                             
/usr/bin/nimsuggest

[blakat360]

I uninstalled nim and re-installed with choosenim. I now get this and the server installs.

% which nim       
~/.nimble/bin/nim
% which nimsuggest 
~/.nimble/bin/nimsuggest

However... vim doesn't seem to detect the nim file type which means that the lsp doesn't attach and when I have the list of possible LSPs it doesn't suggest nimls :(

edit 1: :set filetype=nim makes the lsp autoattach - however there is no syntax highlighting :(

:set filetype=nim makes the lsp autoattach - however there is no syntax highlighting :(

Yeah it'll only start when it finds buffers with the nim filetype. I would assume that neovim had builtin detection for nim files, but apparently not. You can always add the following to your config:

autocmd BufRead,BufReadPost,BufNewFile *.nim set filetype=nim

As for syntax, I assume you're using treesitter for syntax highlighting. I don't believe there's a treesitter grammar for Nim. Maybe you can find some luck with https://github.com/zah/nim.vim?
